- Space cooling
Refer to the menu tree in “Main Settings Menu” for how to check the energy, and “DIP switch functions” for the details on DIP-SW setting.
Either one of the following 2 methods is used for monitoring.
Note: Method 1 should be used as a guide. If a certain accuracy is required, the 2nd method should be used.
(1) Calculation internally
Electricity consumption is calculated internally based on the energy consumption of outdoor unit, electric heater, water pump(s) and other auxiliaries.
Delivered heat is calculated internally by multiplying delta T (Flow and Return temp.) and flow rate measured by the factory fitted sensors.
Set the electric heater capacity and water pump(s) input according to indoor model name and specs of additional pump(s) supplied locally. (Refer to the menu
tree in “Main Settings Menu”)
When additional pumps supplied locally are connected change setting according to specs of the pumps.
When anti-freeze solution is used for primary water circuit, set the delivered energy adjustment if necessary
For further detail of above, refer to “Main remote controller”.
●
Connectable electric energy meter and heat meter
▪
Pulse meter type
Voltage free contact for 12VDC detection by FTC (TBI.3 1, 3 and 5 pin have a positive voltage.)
▪
Pulse duration
Minimum ON time: 40 ms
Minimum OFF time: 100 ms
▪
Possible unit of pulse
0.1 pulse/kWh
1
pulse/kWh
10 pulse/kWh
100 pulse/kWh
1000 pulse/kWh
Those values can be set by the main remote controller. (Refer to the menu tree in " Main Settings Menu".)
(2) Actual measurement by external meter (locally supplied)
FTC has external input terminals for 2 ‘Electric energy meters’ and a ‘Heat meter’.
If two ‘Electric energy meters’ are connected, the 2 recorded values will be combined at the FTC and shown on the main remote controller.
(e.g. Meter 1 for H/P power line, Meter 2 for heater power line)
Refer to the [Signal inputs] in section “6. WIRING DIAGRAM” for more information on connectable electric energy meter and heat meter.
